To all whom t may concern.'

Be it known that I, CHARLESk JfLiETZ,

same, referencel being had to the accom-l panying' drawings, and to the numerals of refercn e marked thereon, which form a part of this specification.

-This invention relates to animproved form of wrapping machine particularly adapted for wrapping caramels, although, of course, adapted to `wrap other similar articles. and by slight modification, capable of wrapping other dilferent objects. The machine embodying my invention is de signed to handle fresh caramelsgin their yieldahle state withoutinjury and as well to talte care of caramels which yvary in size, whereby anfindividual wrapper is applied around each caramel. The machine is de signed for use with a power driveand with the caramel feeding table land discharge chute for the wrapped caramels conveniently arranged for access by a single operator. All parts of the machine are easily accessible for ready adjustment or repair when necessary.

The machine embodying the principles of my invention differs from other types of wrapping machines in many particulars,`

notable amongv which may bementioned the Afart that the article receives the wrap'- per applied upon Vand folded therearound,u

while continuously moved along on a carrying member, with various movable and stationary devices to perform the different folding operations so that the article, when ejected from the carrying member, is completely wrapped.4 K i lt is an object therefore of this invention to provide a wrapping machine adapted to apply and fold a wrapperaround an article during a continuous progress of the article. and furthermore, folding the wrap?.

per upon the article in a new manner whereby thel folds of thewrapperfare interlo^l ed with one another upon the article to obviate subsequent accidental unfolding of the wrapper from the article.

It is alsoan object of this Ainvention to Figure l is a too plan view construct a wrapping machine employing a wrapping wheel which 1s brought to'rest voperation of folding devices which serve to completely fold the wrapper around the article prior to ejection of the article from ythe wrapping wheel. w

It is also an object of this invention to construct la wrapping'marhine wherein an individual wrapper for each article is cut from a continuous reel of wrapping material and properly disposed to receive the article thrust therewith into a wrapping wheel, which then serves by its movement, to carry the article into the held` ofoperation of folding devices which serveto fold the wrapper around the article, certain of said devices over-traveling thel wheel, and others mounted'in stationary position to perform Vthe various folding operations upon the wrapper. f

lt'is a further important object of this invention to construct a wrapping machine wherein an intermittent drive is imparted to certain ofV thek mechanisms through `an improved device for the purpose to permita .continuous application of power to the machine without shock from entrainment of the mechanisms as they areA intermittently operated, thus providing a smooth running mafhine.

--It is alsoan object of this invention to construct a wrapping machinel provided with improved wrapping mechanisms and improved feeding and dischareing devices, as well as an adjustable meansV forV feeding wrappers of any'pr'edetermined size to lthe feeding devizes for application on anv article. l

Other and further` important objects of this invention will be evident'frcm the disclosure in the spccication anl drawings.

which is adapted to'sweep into recesses-1n said Geneva gear as the pin is rotated around with said disk to advance the Geneva gear and its shaft 35, intermittently. The outer end of 'theshaft 32, on which said disk is mounted,

is cut away and curved, as clearly shown in lig. 9, the curved portion registering with the outer peripheral surface of the Geneva gear between the recesses therein as the Geneva' gear is advanced a certain amountY for each rotation of the disk 37. y

Secured upon the outer end of said shaft 35 is a sprocket wheel 39, and trained thereaboutie a chain 40. A bearing bracket 41,

is adjustably mountedon the rear Asurface of the frame plate or arm 23, and jour-r v naled thereinis a notched wheel 42, having notches 43,'therein, as shown clearly in Fig. 23, and around which the yfeed belt 9, is trained. Rigidly but adjustably connected to said belt wheel 42, is a sprocket wheel 44, connected by screws 45, extending through slots in said sprocket wheel into the belt wheel, andsaid driving chain 40 is trained around said sprocket wheel whereby the belt wheel is driven from the driving sprocket 39. The adjustment between the sprocket wheel 44, and belt wheel 42, admitstiming ofthe movement of the belt for `certain positions of other mechanisms of theV wrapping machine hereinafter described, for proper operation thereof.

, Journaled upon said shaft 28, is a largev adjacentto the'worm gear 46, is a ratchet` faced `slidable clutch 49, adapted` to be moved intoV engagement with ratchet teeth formed upon `the hub of the worm gear 46, to lock the worin gear to the shaft 28,

whereby the shaft 28, maybe vchiven-there-i by. Pivoted upon an upright pintle 50, secured on the bearing member 25, 1s a lforked clutch lever 51, the forked end of which engages the groove in the slidable clutch member 49, in order that by actuation of said lever, the clutch may be thrown in or out to lock or unlock the driving gear 46, to or from the shaft 28. A vertically mounted spring impelled detent 52, is mounted at one side on the bearing member 25, beneath the lever 51, and said lever is provided with a downwardly extending projection beveled off on each side at its lower end gainst which said detent bears, to hold said lever either in one or another position tor engaged. or disengaged position of the clutch 49.

ieyed upon said shaft 28, adjacent to the bearing 27, is a cam wheel 54, having one cam groove 55, in one si. face thereof and another cani groove in the opposite surface thereof, l 28, adjacent to said wheel 54, is a bevel gear 57, slightly beyond which said shaft 28, terminates. Journaled in a bearing extension 58, secured upon the front surface of the frame plate 24, is a shaft 59, which extends' ii'iwardly .in alinement with the shaft 28, terminating close to the end oi the shaft 28, and journaled on the adjacent inner ends of said respective shaits 28 and 59, is a spider 60, having an arm extension 6l., and provided with stud shafts 62, diametrically disposed, each having journaled thereon a bevel. pinion 63.' Another bevel gear 64, is secured upon theshai't 59, in mesh with the respective bevel pinions 63. The gears 57, and 64, form a differenti or reversegear drive construction whereby the shaft 59, is driven in reverse direction to, and by the shaft 28, and may be brought to rest and accelerated by adjustment ot the spider carryingthe pinions 63, in a manner hereinafter described.

Secured in upright position upon one side of the frame casting 21, is a bearing standard 65, in which is journaled a shaft 66, which also extends through a bearing formed in the frame plate 24. Connected on the end o said shaft 66, beyond the frame plate 24, is a depending crank 67, for a purpose hereinafter pointed out. Secured upon the other end of the shaft 66, beyond the upright bearing 65, is a crank 68, provided at its end with a roller 69, engaged in the cani groove of the cam wheel 54. Journaled on said shaft 66, on the other side of said bearing upright 65, is a long crank 70, provided near its middle portion with a roller 7l, engaged in the cam groove 56, of the cam wheel Pivotallv connected to the outer end of the crank 70, is a link 72, which is also connected at its other end to the crank 61, whereby movement, of the crank 70, due to travel of the roller 71. in the cam groove 56, imparts an oscillatory movement at certain intervals to the spider 60, carrying the bevel pinions 63. Also secured upon the shaft 59, adjacent the Secured upon the shaft bevel gear 64, is another cam wheel 73, having a cam groove 74, in one surface thereof.

Secured rigidly upon the outer end ot' the bearing 58, of the frame plate 24, is a stationary cam member 75, having a cam groove '(6, in the outer surface thereof. Secured upon the outer end of the shaft 59, which extends through and. beyond said bearing member 58, and cam element 75, is the carrying or wrapping wheel, consisting of a circular .ring 77, with a diametrical cross-piece 78, integral therewith, and on which is formed a hub '79. As shown clearly in detail in F 6, the hub 79, is held attached to a disk portion 80, formed on the end of the shaft 59, by dowel pins 8l, and screws 82. The diametrical cross-piece 7 8,is slotted out for almost its entire length, and slidahle in. said slot is a block 83, having secured on each side thereof and overlapl ping the edges of the crosspiece, plates 84,

held attached by a pin 85, and screws 86. Adjustably attached upon the outer ends of said plates 84, are end folder plates 87, held attached by means of screws 88, en-

ged through slots in said plates to clamp the same in adjusted position. A carrying pocket tor a caramel is formed in the wrapping wheel in that end of the cross-piece 78, at which the end folder plates 87, are

disposed, as shown in detail in Fig. 37. The

walls of said pocket are formed by resilient plates 89, engaged at their lower ends in slots provided therefor, and at their upper ends bent outwardly and then inwardly to engage in recesses 90, provided therefor in the periphery of the carrying wheel., so that when the caramel is thrust into said pocket, said plates are sprung and serve to retain the caramel therein. Slidably mounted through a passage provided through one end of the cross-piece 78, as `shown clearlyin Figs. 5 and 37, is a cylindrical plunger 91, having a head 92, which forms the bottorn'of the caramel pocket inl the wheel, and at its other end is provided with a, head 93, adapted for contact with the upper end of the slide block 83. A set s row is engaged through one side of the cross-piece 78, to engage the plunger and prevent rotation thereof in its passage.

Secured transversely through one end of the block 83, is a pin 94, held attached therein. by a screw 95, and washer 96, and secured i* the end of said pin is a small stud sl` t 97, on'which is journaled a roller 98, which tracks in the cam groove 76, of the stationary cam element 75. Thus, as the wrapping wheel rotates, the roller 98, traveling in the cam groove, will cause the block to slide diametrieally of the wrappingr wheel and thus actuate the end folder plates 87, as well as the ejecting plunger head 92.

Resting upon the upper periphery of the wrapping wheel '77, is a curved or .arcshaped shoe 99, which, for its major por tion, is narrowerthan the surface of the wrapping wheel, but atits forward end is provided with a wide outwardly curved head 100. extending beyond the sides of the wrapping wheel. The rear or trailing end of said siatev 99, is rounded on its outer surface and tapered inwardly to a width less than the siufface of the wrapping wheel, and is denoted b y the reference numeral 101, as shown clearly in Fig. 38. Near its for- *ard end, said shoe 99, is pivotally connected ou u rod 102, which is rigidly but adjustably mounted in a sleeve 103, which is in turn 1, ivoted upon a stud 104, secured in a boss extension on the frame plate 24. Said shoe 99, rests upon the periphery of the wrapping wheel and holds its position by gravity.

.Another curved or arcshaped shoe 105, is spring thrust against the left peripheral face of the wrapping wheel, and the forl Yward end of said shoe 105, flares outwardly and is of lf-shape, shown clearly in detail in Fig. 9&5. the ends of the Vportion, denoted by the reference numerals 10G, spaced apart a distance greater than the width of the peripheral face of the wrapping wheel. The under surface ofsaid V-pointslO, are

- tapered or rounded, as clearly shown in detail in Fig. 39, thus fitting around, though spaced from the tapered portion 101 of the shoe 99. The bevel of the V-points 100 is so designed that the action of one is in advance of the other so that one end fold is bent over slightly in advance of the other as is common in the art so as to prevent the end folds coming together in a jam. Said shoe 105, is pivotally connected on the lower cud of a crank '.07, which is connected on a pintle 1015. secured in lug extensions 109, of a bracket 110. secured. upon the front frame plate 24. A coiled spring 111, is securved around the pintle 10S, and to the crank or lever 107, and acts normally to thrust said lever inwardly to hold the shoe 105, closely against the periphery ofthe wrapping wheel. A wedge shaped block 1111vl is attached to the lower end of the shoe 105, and pivotally connected thereon is a flut resilient metal guide bar 112, which fits over a dir-charge chute hereinafter described, and beneath which `the caramels ejected from the machine are moved.

Also pivotally mounted upon the bracketV 110, parallel to the frame plate 24, are a pair of piutles 113, upon which are pivoted end folder plate arms 114, connected by a spring 115, so as to be'normally drawn to.

in advance of the point at which `the shoe` tostrike the outer portionsof the wrapper as the caramel is Acarried around on the wrapping wheel, prior to the time at which the folder plates .116, contact the wrapper. Thus said breaker' plates initiate the bend in the wrapping material which is completed as end folds by the folder plates 116,'pre-v ventingvpossible injury to the wrapper.

Formed uponthe upper portion at one side of the frame plate 24, is a boss exten' sion 119, through which is journaled a shaft 120, with a pair of folder arms121, adjustably clamped or secured on the outer end thereof by means'of set screws 122. Formed at the lowerends of the arms 121, are end folder heads 123, the inner surface of each of which for contact with the wrapper, is curved smoothly outwardly. The other end of said shaft 120, as shown in Fig. 12, has attached thereon a bell crank having arms 124 and'125, respectively. Connected to the arms 124, is a link 126, which is also connected to the end of a crank 127, pivotedf upon a stud 128, secured in the rear surface of the frame plate 24. Said crank 127, is provided with a roller 128, which projects into the cam groove 74, of the cam wheel 73,v and by travel of the cam 73, receives a dis# tinctive movement, which is transmitted to the bell crank 124-125, and shaft 120, by whch the end folders 121-123, are operate Connected to the arm 125, of the bel crank, is a long link or lever 129, which is connected to a crank 130, secured upon av shaft 131, journaled through an extensionV provided onone side of the frame plate 24. Attached upon the other end of the shaft 131, atthe front of the frame plate 24, as

clearly shown in Figs. 14 to 17, inclusive, i

is a wheel 132, secured adjustably on said shaft 131, by a set screw or other means. Attached upon said wheel 132, is a bent arm 133, having a relatively wide curved surface folder head 134, formedv on the end thereof adapted when'the wheel 132, is oscillated, to strike the wrapper, as shownin Fig. 14, to initiate the first foldthereon. The folder head 134, is operated `co-incidently with the end folders 121-123, the folder head 134, being swung inwardly as the folder heads123, are swung outwardly and vice versa, with respect to the wrapping wheel, due to the fact that the respective folders are both operated from the cam wheel 73. Y.

The. caramels are carried into the rhachine upon the feed belt 9, and as the feed belt stops for an instant due to the intermittent drive thereto, a caramel is thrust into the po ket in the Wrapping wheel with a sheet of wrapping material associated therewith for application around the caramel. For this purpose, attached upon the curved arm extension 23, of the frame plate 22, is a hollow casting 135, having a shelf extension 136, at the forward end thereof, as shown in Fig. 19, and mounted upon said shelf extension is a forming box 137, which is provided with a passage 138, therethrough, the side walls of which are convergent, as clearly shown in Fig. 32.V The top wall of the forming box is formed by a plate 139, the under surface of which over the pas sage 138, is convergent inwardly, and said plate at its rear end is providedwith downwardly extending arms 140, which, as clearly shown in Fig. 33, form a fork for a pivotalconnection of said plate by means of a pintle 141, extending through the forward end of a rectangular frame or casting 142, secured upon the upper surface of the hollow casting 135. Mounted in a beveled slot in said plate 139, is a roller 143, of a diameter greater than the width of the slot so as to rest therein, and a resilient spring member 144, is secured upon the upper surface of the plate 139, and bears upon said roller to confine the roller in said slot. Pivotally connected at the rear end of the plate 139, is a threaded rod 145, which extends through a notched lug 146, formed upon a top plate 147, which is secured over the rectangular frame 142. A washer 148, is engaged on said rod 145, and bears against the notrhed lug 146, and threaded on said rod near the other end thereof is a knurled head 149, with a compression v'spring 150 seated thereagainst and coiled about said rod and bearing on said washer'148, whereby said plate 139, is thrust downwardly by said spring into close Contact with the top surfaces of the side walls of the forming block 137.

Attached acrossV the forward end of the plate 139, and spaced therefrom, as clearly shown in Fig. 19, is a bar 151, affording a breaker strip and guide for the wrapping material introduced in front of the forming box. A similar breaker strip or bar 152, is attached across the front edge of the forming box 137, beneath the passage 138, and spaced from the forming box to re eive the paper wrapper yintroduced therebetween. The caramel feed belt 9, travels beneath the plate 139, in front of the'passage of the forming box, as shown by Figs. 1 and 4.

.As fhawn in Fg. 19, a plunger 153, is

sldalle t"r:uefh the frame 142, and is provided with a head 154. at its foward end.

. Foie ed on the under side of said plunger' is a rack 155, and meshing therewith is a sector gear 157, secured upon a shaft 158, which is journaled transversely through the lower portion of the casting 135. Also secured upon said shaft, shown in Fig. 21, is a crank 159, to which a link 160, is connected, and said link is also connected to a block 161, formed or secured upon a slide bar 162, slidable longitudinally through the lower portion of the casting 135. A link or lever 163, is connected to the forward end of the slide bar 162, and to the lower end of the crank or lever 67, shown in Fig. 8. Journaled on the inner surface of the frame plate 23, within the hollow casting 135, is a bell crank having one arm 164, provided with a roller 165, which engages in a cam groove 166, in the block 161, and the other arm of which, denoted by the reference numeral 167, extends downwardly below the frame casting 135. Plates 168, are attached on the under side of the frame casting 135, at the forward and rear ends thereof, upon which the slide bar 162, rests.

Attached upon the front surface of the frame plate 22-23, as clearly shown in Figs. 4, 7 and 31, is a small casting 169, having one upwardly convex curved top portion 4with a curved housing extension 179. at one side thereof, and with a cover plate 171, attached across the front end of the portion 169. Secured upon the top surface. of the frame member 169, is an angle shaped bracket member 172, shown in Figs. 4 and 27, and secured thereto and projecting upwardly therefrom, and extending downwardly through a slot in the castinc 169, is a paper guide tube 173. Attached upon the upper end of the paper tube 173, is a wide plate 174, with guide channels 17 5, adjustably secured thereon, adjustable for different widths of paper strip. Hthin the casting 169, merely the flat side walls of the tube 173, extend downwardly therethrough, the end walls of the tube only extending into the casing slightly below the top wall thereof. The paper strip is fed upwardly from the guide members 173, between the breaker strips 151 and 152. and interposed in the gap between said guides and said breaker strips is a paper shearing mechanism.

This mechanism is supported upon the forward portion of the frame casting 21. and for thispurpose, as shown in 7 and 43. a bracket 176, is secured upon said frame casting 21. and mounted in uprifrht position therein is a shaft or rod 177. Adiustahlv mounted upon the upper end of said shaft 177, for slidable adjustment with respect thereto, is a bracket 178, held from rotation thereon by a key 179, formed or secured on the shaft 177. An upright threaded shaft or bolt 180, is mounted in the upper end of the bracket 176, and has threaded engagen'ient with the bracket `178, whereby rotation of said threaded rod will serve to elevate or lower the bracket 178. Rigidly secured upon an extension of the bracket 178, is a horizontally disposed shearing blade 181, and disposed toco-act therewith in shearing the paper is a pivotal shearing blade 182, secured uponan upright shaft 188, journaled in said bracket 178. Attached upon the lower end of said shaft 188, is a crank 18a, to which the forward end of a link or lever 185, is connected. The lever 185, is also connected to the depending crank 10T. lfhus the oscillations imparted to the crank 167, will servo to operate the pivoted shearing blade 182, to cut the paper strip at that point between the upper end of the paper guide and the lower breaker' strip 152, of the forming box.

vAttached to or formed upon the angle bracket 172, are uprights or bearing blocks 186, in which a pair of connected receiving arms 187, for the ejected wrapped caramels are pivoted. As clearly shown in Fig. 41, a coiled compression spring 188, is mounted beneath said connected arms 187, bearing upwardly therebeneath, and is seated upon the upper surface of the frame casing 169, and acts normally to thrust said arms 187, up wardly into contact with the lower periphery of the wrapping wheel 7 7. Journaled through an extension on the frame plate 22, is a shaft 189, having secured on its outer end a crank 190, to which a link 191, is con nected. rl`he other end of said link 191, is connected to a lever 192, pivoted upon a stud 193, as shown in Fig. A. Pivoted adjacent to said lever' 192, is anotherlever or crank 194;, and said levers are connected to one another at their upper ends by a link 195, which maintains a substantially horizontal position in all its movements for pivotal adjustments of said cranks. The forward end of said link 195, is formed with an ejecting head 196, for the caramels discharged from the wrapping wheel, and said head extends outwardly on each side and slides upon the upper surfaces of said levers 187, between which said links and said cranks 192 and 194, are disposed. `Said respective cranks are actuated at the proper instant to eject a wrapped caramel due to a drive imparted to the crank 190, shown in Fig. 27, on the shaft 189. For this purpose, secured ou the inner end of the shaft 189, is a gear 197, which meshes with gears 198 and 199, shown in Fig. 12, the latter jour naled on the stud on the rear surface of the frame plate 24, and the idler gear 199, meshes with a driving gear 200, Vwhich is secured upon the end of the shaft 59, adjacent to the frame plate 211. Mounted within the frame member 169, are the paper feed rollers of the wrapping machine. For this purpose, as shown in Fig. 28,a shaft 201, is journalcd in bearings provided in eXtensions of said frame casing, and secured thereon are frictionrolls 202, four in number, and at the inner end of said shaft is a gear 203. Said gearineshes with another gear 2041, secured upon a shaft 205, j ournaled through the frame plate 22, and at its inner end has secured thereon the gear 198, previously mentioned, and shown in Fig. 12.

As shown in Figs. 29 and 30, lug extensions206, are formed upon one side of the inner surface of the frame casing 169, and journaled therein isa shaft 207. Secured upon said shaft 207, is a long bracket 208, having journaled therein a tubular member 209, provided at one of its ends with an integral friction roll 210, having secured centrally thereon friction rolls 211. Secured on the forward end of the tubular member 209, is another friction roll 212, provided with an integral knurled adjusting head 218, extending outwardly through an aperture in the cover plate 171. A shaft^2141, extends through said tubular member 209, and at its inner end is provided with a gear 215, mesh-` ing with the gear 208, and the other end of said shaft is threaded and has secured there on a locking knurled head 216, beneath which is mounted a washer 217, and a collar 218, threaded upon the end of the tubular member 209, and bearing against the fric- .tion roll 212. Secured upon the end of the shaft 207, is a depending crank 219, shown in Figs. 29 and 30, and connected thereto, as shown in Fig. t, is a link 220, which is in turn connected to 'a bell crank having one arm 221, and another arm 222, said bell crank being pivoted upon a stud 228, inthe front surface of the frameplate 22. A handle 2241, is slidably mounted in the end of the crank 222, adapted to engage in either one of two apertures in a bracket -225, secured upon Vthe frame plate 22,'to hold said bell crank in either one of two adjusted positions.

As 'clearly shown in Fig. 29, the respective friction rolls within said casing 169, are cut away for a portion of their periphery so that the extent of rolling contact surface between the opposite rolls may be lchanged by adjustment of the friction rolls which are mounted upon the tubular member 209. As clearly shown in Figs. 28 andV 29, threaded members 226, are engaged through the side wall of the casing 169, and at their inner ends have seated thereagainst coil compression springs 227, which bear against the carrying bracket 208, for the friction rolls, normally thrusting the same against .the friction rolls 202.

Fivoted upon a stud shaft 228, secured in an extension of the lower vend of the paper tube or guide, are a pair of arms 229, between which. is ournaled a roller 280, which is normally thrustV inwardlyv against the inner surface of one wall of the paper' tube or guide, and beneath which the paper strip
